Who had the best one-liners at the Senate’s climate slumber party?

Thirty U.S. senators pulled an all-nighter on Monday. They did not, sadly, wear PJs, paint toenails, or fight with pillows.

Instead, they talked about climate change — and talked and talked and talked. They cited studies and stats. They showed photos and graphs. They warned about climate impacts in their home states. They promoted the economic benefits of clean energy and the job-creating potential of innovation. They made strained analogies about baseball and the rise of the Nazi regime. Altogether, they talked for nearly 15 hours, right through to 8:55 a.m. Tuesday morning.

There aren’t enough votes in Congress right now to pass strong climate legislation, or any climate legislation (though an energy-efficiency bill might squeeze through). But at least nearly a third of senators care enough about the problem to stage the 35th all-nighter in Senate history.

“Tonight is not about a specific legislative proposal,” said Sen. Sheldon Whitehouse (D-R.I.), one of the organizers of the talkathon. “It’s about showing the environmental community, young people, and anyone paying attention to climate change that the Senate is starting to stir and we want to get some actions going.”

Whitehouse — a passionate climate hawk who has now given 60 speeches about global warming on the Senate floor — orchestrated the chatfest along with Sen. Brian Schatz (D-Hawaii), under the aegis of the new Senate Climate Action Task Force. Both of the Senate’s independents joined in, as well as 26 other Democrats, including, as The Guardian points out, “several senior Democrats who have not spoken out publicly before on climate change.”

The only Republican to show up was more than a little off-message. Sen. James Inhofe (R-Okla.), the Senate’s No. 1 climate denier, gave a rambling speech arguing, among other points, that it’s been cold recently, therefore global warming is a hoax.

To which Schatz replied: “Pointing out a window on a cold day and laughing about climate change is one of the most profoundly unserious things that otherwise good and responsible leaders in this chamber do.”
